Answer: B. 50 and 60

Step-by-step explanation:

Given : There are 9 showings of a film about endangered species at the science museum.

The total number of people saw the film = 459

Also, The same number of people were at each showing.

Then, the number of people were at each showing = Total people divided by Total showings

= 459 ÷ 9 = 51

Also, 50< 51 < 60  [the quotient is between 50 and 60.]

i.e.  About 50 and 60 people were at each showing .

Hence, the correct answer is B. 50 and 60.

the first simple interest will be $1.73 more than the second one.

<h3>Which is the difference between the two interests?</h3>

The loan is of $575, and there are two options:

7 years at 4.5% or 8 years at 3.9%

Remember that the simple interest formula is:

SI = (P*R*T)/100

Where:

P = principal value.

R = rate (this is the percentage per year)

T = time, in years.

Then for the first option. the interest will be:

SI = ($575*4.5*7)/100 = $181.13

For the second option we will have the interest:

SI'  =( $575*3.9*8)/100 = $179.4

The difference is:

$181.13 - $179.4 = $1.73

This means that the first simple interest will be $1.73 more than the second one.
